Fully printable plasticized fluorinated terpolymers for mirror active morphing control

Year: 2025

Type: article

Abstract: The use of plasticized P(VDF-TrFE-CFE), a relaxor ferroelectric polymer, has shown major improvements over thepast few years. Dedicated to telescopes active optics actuators for the Live-Mirror project, the analysis of the plasticizer(here, DNOP) interaction with various polymer matrixes for high permittivity and softness is investigated here. The amountof termonomer not only leads to a low crystalline fraction but also increases the number of amorphous – crystallineinterfaces where it can accumulate and get trapped. The obtention of large S33 of 2.5% at 30V/μm (here 6μm), measuredby interferometry, vows great displacements for 4D-printed multilayer actuators.
